We're pleased to present to you this year's Annual Quality Water Report. This
report is designed to inform you about the quality water and services we deliver to you every day. Our constant goal is to
provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to continually
improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water.
Our water source is three wells, located within our city limits that we chlorinate with food degradable sodium hypochlorite. We also use a sequestering agent for iron and manganese control, this year we did
some in house testing that showed that our water needed less of this sequestering agent and were able to reduce the amount
we use. We believe that if we don’t need to add more than our water needs so why put it in at past quantities as long
as we still meet quality standards.
We have a source water protection plan available
from our office that provides more information such as potential sources of contamination.
Also available is our Wellhead Protection Plan that will insure the public is provided with sustainable safe drinking
water supply and to reduce the potential risks of contamination.
The City was granted in 2007, a chemical monitoring waiver for the 2008-2011 compliance period for synthetic organic
chemicals (SOC) and dioxin. These waivers apply to our three wells. The estimated
cost savings is $1600 for our water system.
In 2007 an
Emergency Response Plan and a Security Vulnerability Assessment were developed for our water system as required by Rural Development.
This report shows our water quality and what it means. If you have any
questions about this report or concerning your water utility, please contact Bob at 582-1530.
We want our valued customers to be informed about their water utility. If you want to learn more, please attend any
of our regularly scheduled meetings. They are held on the first Tuesday of the month at 7:00 p.m. at Harrison City Hall.
City of Harrison routinely monitors
for constituents in your drinking water according to Federal and State laws. This table shows the results of our monitoring
for the period of January 1st to December 31st, 2008. As water travels over the land or underground
it can pick up substances or contaminants such as microbes, inorganic and organic chemicals, and radioactive substances. All drinking water, including bottled drinking water, may be reasonably expected to
contain at least small amounts of some constituents. It's important to remember
that the presence of these contaminants does not necessarily pose a health risk.
In this table you will find many terms
and abbreviations you might not be familiar with. To help you better understand these terms we've provided the following definitions:
(ND) - laboratory analysis indicates that the constituent is not present.
per million (ppm) or Milligrams per liter (mg/l) - one part per million corresponds to one minute in two years or a single
penny in $10,000.
per billion (ppb) or Micrograms per liter - one part per billion corresponds to one minute in 2,000 years, or a single penny
per trillion (ppt) or Nanograms per liter (nanograms/l) - one part per trillion corresponds to one minute in 2,000,000 years,
or a single penny in $10,000,000,000.
per quadrillion (ppq) or Picograms per liter (picograms/l) - one part per quadrillion corresponds to one minute in 2,000,000,000
years or one penny in $10,000,000,000,000.
per liter (pCi/L) - picocuries per liter is a measure of the radioactivity in water.
per year (mrem/yr) - measure of radiation absorbed by the body.
Fibers per Liter (MFL) - million fibers per liter is a measure of the presence of asbestos fibers that are longer than 10
Turbidity Unit (NTU) - nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTU is
just noticeable to the average person.
& Exemptions (V&E) - State or EPA permission not to meet an MCL or a treatment technique under certain conditions.
Level - the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system
Technique (TT) - (mandatory language) A treatment technique is a required process intended to reduce the level of a contaminant
in drinking water.
Contaminant Level - (mandatory language) The “Maximum Allowed” (MCL) is the highest level of a contaminant that
is allowed in drinking water. MCLs are set as close to the MCLGs as feasible
using the best available treatment technology.
Contaminant Level Goal - (mandatory language) The “Goal” (MCLG) is the level of a contaminant in drinking water
below which there is no known or expected risk to health. MCLGs allow for a margin
